obama's weak debate performance. here was president barack obama today. >> this morning we found out that the unemployment rate has fallen to its lowest level since i took office. (cheers) >> more americans entered the work force, more people are getting jobs. >> and here is governor romney's reaction to the same number. >> the reason it's come down this year is primarily due to the fact that more and more people have just stopped looking for work. and if you just drop out of the work force, if you just give up and say i can't go back to work, i'm going to stay home and drop out altogether, why, you're no longer part of the employment statistics, so looks like unemployment is getting better. but the truth is if the same share of people were participating in the work force today, as on the day the president got elected, our unemployment rate would be around 11%. >> the president clearly sees today's numbers good news for his campaign, but eric you've been digging into the numbers. can you help us dig a little deeper.
